Stylized 3D, vertical 9:16. Nastya (match master_nastya.png) walks
through the laughing classroom to the chalkboard, head down, hood
up, and reaches to untie her sneakers from the string; chalk
caricature beside her face. Classmates' phones (match
master_classmates.png, blurred) point at her. The walk of shame,
harsh light, her small figure against the big board. No on-screen
text.
